Green Facilities at ASE

Reducing Critical GHG Emissions

According to studies conducted by the United Nations, building construction and usage account for 40%, 25% and 40% of total global consumption of energy, water resources and other resources, respectively; furthermore, greenhouse gases emitted by buildings account for one third of total global greenhouse gas emission, indicating that buildings are among the most critical points for implementing energy conservation and carbon reduction.

Managing Our Operational Environmental Footprint

As ASE continues to grow and expand our production capacity, our operational environmental footprint has proportionately increased. In order to achieve sustainable growth, ASE stayed focused on reducing operational environmental footprint by enhancing resource efficiency and reducing emissions of pollutants.

Creating a physical environment that promotes awareness for sustainability

Green buildings not only provide a healthier and more comfortable working environment for our employees, but also are concrete illustrations of our dedication to sustainable operations. Through using and passing through the green buildings daily, we expect ASE’s employees to not only recognize ASE’s determination to realize the vision of sustainable business, but also improve their understanding of sustainable development as well as bring sustainability into their lives, deepening all employees’ awareness for sustainability.

What are green buildings?

Green buildings refer to buildings that meet the environmental-friendly criteria and achieve effective use of resources in all phases of their lifetime, including site selection, design, construction, operation, maintenance, renovation and even demolition. Both existing and new buildings can be certified with green building label.

Glossary of Green Buildings

LEED
This green building certification system was officially launched by U.S Green Building Council (USGBC) in 1998, and is so far the most frequently used system worldwide. Assessment categories include sustainable sites, water efficiency, energy and atmosphere, indoor environment quality, innovation and design process, and regional priority; LEED certification levels are divided into 4 levels: certified, silver, gold and platinum.
EEWH
This Taiwanese green building label was implemented in 1999, and is the world's second green building certification system ever implemented (only second to LEED). The assessment categories are ecology(E), energy saving (E), waste reduction (W) and health (H). The certification levels are divided into: qualified, bronze, silver, gold and diamond.
Intelligent Building Certification
Establishing the person in charge of regulatory identification in respective responsible departments at each site, and authorizing such person in charge to confirm that site's operations are conforming to applicable laws and regulations and to report the state of compliance to his or her superior.
Green Factory Label
This certification is conducted by the Industrial Development Bureau (IDB) of the Ministry of Economic Affairs (MOEA). The factories that wish to be certified with this label need to acquire both the "green building" and "clean production" certifications. The production process of a green factory shall be in line with environmental protection characteristics, including energy resource conservation and low pollution.

Characteristics of Green Building

If the green buildings are brand new buildings, the design considerations shall cover all of the following items. If they are modified from existing buildings, the focus shall be placed on daily energy conservation.

Design methods
  • Multi-layered planting and ecological retention basin
  • Ecological fence and porous space
  • Ecological corridor
  • Rooftop garden
Effects
  • Enticing birds and butterflies
  • Building an ecological network system (ecological restoration)
  • Improving base microclimate
Ecological retention basin

Ecological fence

Design methods

Sponge (Breathable) Road -JW Eco-Technology: High load-bearing structure type of permeable concrete pavements are filled in breathable plastic conduit frames. Breathable pipes are densely distributed on the surface layer and are linked to the coarse materials in the bottom to provide excellent breathability, permeability, water retention and water storage.

Effects
  • 40%-78% of vehicle exhaust emissions could be directly or indirectly absorbed
  • Service lifetime is 10 times longer than conventional permeable pavements
  • Increasing rainwater recycled: water permeability of pavement
  • Groundwater storage tank is established and the total rainwater recycling storage capacity reaches 238 metric tons
  • Pavement temperature can be
  • 20°C lower than that of asphalt pavement, thus reducing urban heat island effect

Design methods
  • Use air handler (also known as a makeup air unit (MAU)) to draw air from outdoors and install a flow meter to monitor the amount of outdoor air drawn in
  • Install CO2 sensor
Effects
  • Ensuring indoor air quality for staff staying indoor over a long period of time
  • Avoiding CO2 concentration getting too high and making indoor staff uncomfortable
Design methods
  • Install power system to monitor and control operating status
  • Optimize operational control to ensure equipment operates in the most effective state
Effects
  • Tracking the operating parameters of power system and compare predicted and actual energy consumption to review and identify optimal operation control mode
Design methods
  • Apply high-reflectivity coatings on rooftop surfaces
  • Install green rooftop
  • Reduce hard pavements and increase area of greenery
Effects
  • Reducing urban heat island (UHI) effect
  • Reducing indoor temperature
Design methods
  • Use high-efficiency chiller, cooling towers and add VFD (variable frequency drive) to cooling tower fans
  • CDA heat recovery system
  • Use dual-temperature and high-temperature difference systems for chiller circuit
  • Use high-efficiency FFU
  • Optimize MAU control mode
  • Install top plate insulation
Effects
  • Lowering electricity consumption by air-conditioner’s electricity consumption by approx. 40% than international standards
Design methods
  • High-efficiency T5 & LED lighting
  • Low power density design for indoor lighting
  • Install independent lamp control or multi-stage dimming control for public space, such as meeting room, lobby, etc.
Effects
  • Lowering indoor lighting power density by 70% than international standards
  • Using dimming control mode to avoid ineffective use of lighting

Office independent lamp control

Design methods
  • Reduce daily water consumption: Install high-efficiency water-saving sanitation equipment and recycle rainwater and air conditioning condensation
  • Water-saving landscape design: Install multi-layered planting of indigenous drought-tolerant species and rainwater raft foundation
Effects
  • Substituting 100% of irrigation water with rainwater
  • Achieving daily water-conservation rate of approx. 50%
  • Reducing water consumption for planting

In addition to leading by example and committing to reducing environmental footprint of our own operation, as the leading independent provider of semiconductor manufacturing services in assembly and test, we aim to maximize our positive influence by sharing our experience and success on green building development.

Through participation at local and international symposiums, collaboration with industry organizations and cross-visits to other green buildings, we aim to learn and share more information and expertise on how to design a brand new green building or transform existing buildings into green buildings.
